创建3D场景至少需要三个关键组件：模型，材质和灯光.在这部分中我们首先讨论建模. Modeling is simply the art and science of creating a surface that either mimics the shape of a real-world object or expresses your imagination of abstract objects.
Modeling can take many forms in Blender depending on the type of object you are trying to model. Some objects are not able to be modeled, these being:
- Speakers
- Cameras
- Lamps
根据您尝试建模的对象类型，有不同类型的建模模式。 由于模式不是建模特有的，因此它们在手册的不同部分中都有介绍。
Edit mode is the main mode that modeling takes place. Edit mode is used to edit the following types of objects:
- Meshes
- Curves
- Surfaces
- Metaballs
- Text objects
- Lattice
Because each of these are different types of object they have different types of transforms and therefore have different set of tool. Because of this each has its own section described below.
Mesh Modeling
Typically begins with a Mesh Primitive shape (e.g. circle, cube, cylinder…).
Curve Modeling
Uses control points to define the shape of the curve.
Surface Modeling
Similar to curve modeling, but instead of being limited to simple linear paths, they allow the creation of three dimensional surfaces, potentially with volume.
Metaball Modeling
Begins similarly to mesh modeling (see above), with a base shape like a cube or sphere, but instead of extruding these base shapes, these objects are clumped together to form a larger object. In order to accomplish this, the metaballs have a liquid-like quality, when two or more are brought together, they merge by smoothly rounding out the point of connection, appearing as one unified object.
This can also be a quick way to get started with a rough shape which can be converted to a mesh later.
Text Modeling
Text modeling is an easy way to create logos and to simply add text to a scene.
Modifiers
Modifiers are automatic operations that affect an object in a non-destructive way. With modifiers, you can perform many effects automatically that would otherwise be tedious to do manually.
